Hi,
i found in the Archives:
http://www.sunmanagers.org/pipermail/sunmanagers/2001-April/003390.html
but no Summary until now.
My Problem has to do with this, too:
I have some linux hosts behind a masquerading firewall. The hosts do
some nfs-mounts, and use YP from a multihomed Server (SunOS 5.5.1).
The client's UDP packet (i.e. request for NFS or YP) goes through the
firewall (masq-ed) passes some Routers and arrives at the server.
The Server answers with an UDP packet. But the source address in that
packet is often one of the other interfaces the server. That is a
problem for the firewall doing that NAT thing, because it does not
expect an answer from a different IP address and throws the packet away
instead of sending it to the client.
So I have the effect that sometimes the requested Service is reachable,
but mostly not.
Is there a way to make that the server sends his answer packet out on
that interface where the request arrived?
thanks in advance
Dirk
